PDGFRB and non-small cell lung carcinoma: MiR-34a/c enforced expression reduced migration and invasion of Calu-6 cells but overexpression of PDGFR-α or PDGFR-β, along with the two microRNAs, partially restored the migration and invasion capabilities, suggesting that miR-34a/c regulate NSCLC tumorigenesis, at least in part, through PDGFR-α/ β (Figure 6 d,e).
